To all whom it may concern.

Be it known that I, WILLIAM F. JVATKINs, a citizen of the United States, residing at Seattle, in the county of King and State of Vvashington, have invented certain new and useful Improvements in WVindoW-Sash- Holding Devices, of which the following'is a specification. p

My invention relates to improvements in window sash holding and antirattling devices and the object of my improvement is to provide a window sash holding device that is cheap, simple and strong in construction, neat and ornamental in appearance, that is adapted to be permanently secured to the ordinary type of window sash and that will prevent rattling of a window sash and also serve as a friction lock to prevent raising or lowering of the window sash.

Another object is to provide a device of this type in the nature of a cheap and simple article of manufacture that may be sold as an attachment and that does not require any skill to install.

lVith the above and other objects in view as will be apparent from the following description the inventionconsists in the novel construction, adaptation and combination of parts of a window sash holding device as will be more clearly hereinafter described and claimed:

In the. accompanying drawings Figure 1 is a plan view of a window sash holding device constructed in accordance with this invention. -Fig. 2 is a view in edge elevation of the same. Figs. 3, 4 and 5 are views in cross section of the same on broken lines 3, 3 4, 4 and 5, 5 respectively of Fig. 1 and Fig. 6 is a fragmentary view in elevation of a window showing two of these devices installed thereonl Like reference numerals designate like parts throughout the several views.

Referring to the drawings I have shown a window sash holding deviceformed of a single piece 7 of relatively thin resilient metal having a straight forward edge 8, rounded ends 9 and 10 and a rear edge comprising two rearwardly projecting lug portions 11 and 12 near the ends 9 and 10 respectively and separated from each by an indentation 13.

location of the lug The lug 11 is 'providerlwitli a perforation to M through which a rew 15 may be inserted i to secure the device to a window sash 16 that is movable vertically between stops 17' of the usual form in a window 18sec Fig. 6.

The plate 7 is provided with curved spring like friction members 20 and 21 that are stamped out of the body of such'plate and bent to substantially the curvature shown in Figs. 4: and 5.

The rear'edgeof theplate is bent up-,1 v wardly substantially as shown to form a relatively narrow curved flange 22 at the wider flange 23 at the outer 12, see Fig. 5. t

The narrow flange. 22 serves to reinforce and strengthen the plate 7 and to give the edge of the lug 6 11 and recess 13 and a same greater rigidity and such flange at the location of the recess 13 also serves as a means for engaging with or strikingagainst The configuration of the rear edge of the plate 7 and the gradual curves of the flanges 22 and 23 give the device an ornamental ap-' pearance.

The devices may be'made right and left hand respectively for the two sides of a window or they may all be made identical and the position of the same reversed for the two sides of a window, for instance, ininstalling of a Window the screw that holds the same will be at the upper end while for the opposite side of the; window the device will be inverted and the screw that holds the same will be at the lower end.

' When the devices are installed the screws, V i that hold the same are preferably turned sufficiently tight to hold the devices in any angularposition into which they may be at justed. 1 v

In use two of the plates willpreferablybe secured to each side of each wlndow sash-16 adjacent the stop 17 that forms a guide for I.

90 the device shown in the'drawings on one side 1 such sash. When turned into the lowermost position shown in Fig. 6 the devices will be inoperative but when it is desired to frictionally lock the sash against raising or lowering movement and to prevent such sash from rattling the holding devices will be turned into the uppermost position shown in Fig. 6

in which position they will act as resilient wedges between the window sash 16 and stops 17.

may be made as are within the scope of the following claim.

What I claim is:

A window sash holder comprising a relatively thin metal plate having a rear edge provided with a centrally located indentation that forms a rearwardly projecting lug near each end, one of said lugs having a perforation therein, a reinforcing flange formed by bending the rear edge of said plate upwardly around said lugs and said indenta tion said flange at the location of said indentation being narrow and forming a stop and at the location of one of said lugs being wider and forming a fingerhold, and curved spring like friction members integral with the body of said plate-and located near the front edge thereof.
